METAL-WHEEL CONSTRUCTION.

Application filed October 29, 1914.

T o all whom tmag/ concern Be it known that I, JosnrH L. Hncn'r, a citizen of the United States, residing at Davenport, in the county of Scott and/State of Iowa, have invented certain new and useful Improvements in lletal-lVheel Construction, of which the following is a specification, reference being had therein to the accompanying drawing.

Thisinvention relates to means for connecting parts or members fixedly together, and has reference more particularly to the connection of the parts of metal wheels, that is, the connection of the spokes, either to the hub or tire or both.

The aim of the invention is to so connect the spokes that the parts of the wheel Will be joined with great strength and rigidity, and

Without danger' of disconnection, displacement or l-ooseness, and with this end in view the invention consists in providing the spoke with an over-hanging annular portion or flange, and in providing the adjacent member of the wheel, either the hub or tire or both, with a projecting hollow boss, which latter surrounds the spoke and Ihas its end seated within the overhanging' flange, the spoke being provided also with an enlargement seated in the boss. As a result of this construction, the end of the boss will be `embraced and reinforced by the flange, andv prevented from spreading in the event of the spoke being subjected to endwise tension or pressure tending to. force the enlarged portion through the boss.

In the accompanying drawings: Figure l is a longitudinal section through a wheel having my invention embodied therein in its preferred form. Fig. 2 is an end elevation of the hub of the wheel and the connected ends of the spokes. Fig. 3 is a longitudinal section of a hub and connected spokes, showing the invention in modified form. Fig. 4 is au end elevation of the saine. Fig. 5 is a sectional elevation Ashowing a modified forni of a detail.

v lleferring to the drawings', referring'` to Figs. l. and l represents a metal nheel hub, preferably in the foi-in of a section of Specification of Letters Patent.

steel tubing, which is provided at intervals therearound with Va series f hollow hub bosses 2 projecting radially liut\va1'd therefrom. These bosses may be formed in any appropriate manner or by any appropriate means, but I prefer to form them by punching or throwmg ther metal outwardly so as to produce tubular projections formed integrally with the hub body. Secured within the bosses are spokes 3, each provided near its inner end with an annular 'flange 4 overfirmly at its end within the boss, and the latter will be reinforced by the over-hanging embracing flange, and by reason of the enlargedY portion of the spoke seated within the boss, the displacement of the spoke in a radial direction outwardly will be prevented, aSY the tendency of such displacement to expand the boss will be resisted and prevented by the surrounding flange on the spoke embracing the end of the boss. The boss is therefore effeetually reinforced by the overhanging flange, and the spoke is fixedly and rigidly held within the boss'froin movement in both directions. radially. The outer ends of the spokes may be connected with the tire 7 in any suitable manner, but in the drawv ings I have shown the saine method of attachment as that just described. the tire being provided ith an inwardly extending hollow boss 2. and the spoke with an overhanging flange Il embracing the end ofthe boss. and provided also with au enlargenient or shoulder l seated within the boss.

Fig. ll shows a modified forni of the invention, which is embodied in the connection of the spokes with the hub. lnvthis iug flange on the lpole serves to reinforce the boss, and prever ds its spread 1r the event of the spoke bein g subjected to endwise pressure or strain.

-vWhile l have de. x'xibed the overhanging portion of the spot 'e asan annular flange,v

which in Figs. 1, 2 a ud 3 is shown as having its edge continuous, this continuous edge is not -absolutely neces sary, because the overhanging embracing portion could be constructed in the form of fingers or teeth es shownin Fig. 5, prot lueing in ellect an an nula-r groove in the spoke extending.' axially of the same.

The invention is applicable either to the attachment of the spol 'es to the hub member of the whe-el, or to the tire member, or both, and is applicable also lgenerally to the connection of parts of oth er constructions, and wherever a firm and i'igid union between the parts is desired.

I have in the accompa nying drawin gs and foregoing description d isclosed my inven tion in the particular del :ailed form which I prefer to adopt, but it will be understood that these details may be variously eh ange-d and modified without departing from the scope of the invention; and further it will be understood that the invention is not 4o limited to any particularA form or construc` tion of the. parts except in so far as: such limitations are .specified iii the claims.

Having thus describediny inventiomwhat I claim is: i

1. ln combination'witll a member provided with a projecting hollow boss, a second member extending wifghin said boss and provided with an overhanging am iular flange embracing the end oli the boss and restraining the same against lateral spread,

,said second-member 'being also provided with an annular enlargement-seated within the boss. Y 2. In a wheel, the combination of a spoke provided with an annular'tlange forming an annular groove'surroundir; g the spoke, an adjacent member of the wheel formed with a hollow boss surrounding the spoke and having its end seated and confined in` the groove and restrained by the i'iange against lateral spread, the portion of said spoke within the boss being greater in cross-see tional extent than the internal diameter:

of the confined end of the boss. n 5.-; il. ln a wheel. thc combination of a spokeprovided with angannular flange extending axially thereof and forming an axiallv extending annular groove surrounding the spoke, and an adjacent member of the wheel provided with a projecting hollow-boss surrounding the spoke and extending axially of the same and having its end seated and conlined in the groove in the spoke.

l. ln a wheel, the combination of a spokeprovided with an annular flange extending axially thereof. and forming an axially ex- A tending annular groove surrounding the spoke, and an adjacent member of the wheel provided with a hollow project-ing boss extending axially of and surrounding the spoke, said boss having its end seated in the groove in the spoke, and said spoke being provided also with a shoulder seated within the boss.

5. In a wheel, the combination of a hub provided with a projecting hollow spoke boss, and a spoke seated therein and having an annular axially extending flange forming an axially extending groove in which the end of the boss is seated and confined against lateral spread.

0. In a Wheelg the combination' of a hub provided with a. projecting-hollow spoke boss, and a spoke seated therein and having an annular axially extending flange forming an axially extending groove in which the end of the boss is seated and confined against lateral spread, said spoke being pro,- gided also with an enlargement seated in the oss. l

7. In a Wheel, the. combination of a hub having an outwardly, .projecting hollow spoke boss, and a spoke extending within said boss and. having outward of its end an annular axially extending flange forming an axially extending annular groove in which the end of the bossis seated and restrained against lateral spread.

8.111 a wheel, the combination of a hub having an .outwardly projecting hollow spoke boss, and a spoke extending within said boss and'having. outward of its end an annular axially extending fiange forming an axially extending annular groove in which the end of the boss is seated and restrained against vlateral spread, the inner end of the spolie Within the boss being enlerged.
